The invention discloses a stable one-section two-step extension ladder, and belongs to the technical field of ladders, the stable one-section two-step extension ladder comprises a plurality of pairs of ladder pipes which are sleeved and connected step by step, a plurality of connecting sleeves, a plurality of pedals, a locking structure and hand supporting rods, the outer sides of the ladder pipes are provided with supporting hook holes, and the connecting sleeves slidably connected with the ladder pipes are provided with supporting hooks matched with the supporting hook holes; when the ladder pipes and the connecting sleeves slide, the supporting hooks are clamped into the supporting hook holes, the ladder pipes can support the connecting sleeves, the ladder pipes and the connecting sleeves are smoothly locked, stable locking of the second step pedal is achieved, the head of the lowest ladder pipe is sleeved with the hand supporting rods, the hand supporting rods are connected with the ladder pipes in a sliding mode, and when the hand supporting rods are supported, the ladder pipes can be rapidly unlocked and contracted. And the folding efficiency of the one-section two-step extension ladder is improved.
本发明公开了一种稳定的一节二步伸缩梯，属于梯具技术领域，包括若干对逐级套合连接的梯管、若干连接套、若干踏板、锁定结构和手托杆，梯管外侧设有托钩孔，与梯管滑动连接的连接套设有与托钩孔匹配的托钩，当梯管与连接套产生滑动时，托钩卡入托钩孔内，梯管能够把该连接套托起，梯管连接套顺利锁定，实现了第二步踏板的稳定锁定，手托杆套于最下一节梯管头部且与梯管滑动连接，托起手托杆时梯管能够快速解锁收缩，提高一节二步伸缩梯收起时的效率。
